NCP4626
300 mA, Low Dropout
Voltage Regulator with
Reverse Current Protection
The NCP4626 is a CMOS 300 mA low dropout linear regulator with
a wide input voltage range of 3.5 V to 16 V, low supply current and
high output voltage accuracy. Through an ECO mode selector pin the
device can be operated in low power mode to reduce quiescent current
or fast mode for better transient response and lower dropout. The
NCP4626 is suitable for applications where the VOUT pin voltage
may be higher than the VIN pin voltage as it is protected against
reverse current. The device has a maximum input voltage tolerance of
18 V, comes with or without an auto−discharge feature on the output,
and is available in a choice of XDFN, SOT89 and SOT23 packages.

APPLICATION INFORMATION
A typical application circuit for NCP4626 series is shown
in Figure 84.
current capability in normal operation, but when over
current occurs, output voltage and current decrease until
over current condition ends. Typical characteristics of this
protection type can be observed in the Output Voltage versus
Output Current graphs shown in the typical characteristics

ECO Function
The IC can be switched between two modes by ECO pin.
One mode is low power mode, where IC’s self current
consumption is low, but IC has slower dynamic behavior or
in to fast mode, where current consumption is higher, but the
IC has better dynamic response and lower dropout voltage.

Thermal Considerations
Input Decoupling Capacitor (C1)
As power across the IC increases, it might become
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design and layout. Mounting pad configuration
on the PCB, the board material, and the ambient temperature
effect the rate of temperature rise for the part. That is to say,
when the device has good thermal conductivity through the
PCB, the junction temperature will be relatively low with
high power dissipation applications.
The IC includes internal thermal shutdown circuit that
stops the regulator operating if the junction temperature is
higher than 150°C. After shutdown, when the junction
temperature decreases below 130°C, the voltage regulator
would restarts. As long as the high power dissipation
condition exists, the regulator will start and stop repeatedly
to protect itself against overheating. Care should be taken in
the PCB layout to try to avoid this temperature cycling
condition.
A 2.2 mF (or larger) ceramic input decoupling capacitor
should be connected as close as possible to the input and
ground pin of the NCP4626. Higher capacitor values and
lower ESR improves line transient response.
Output Decoupling Capacitor (C2)
A 4.7 mF (or larger) ceramic output decoupling capacitor
is sufficient to achieve stable operation of the IC. It is
necessary to use a capacitor with good frequency
characteristics and low ESR. The capacitor should be
connected as close as possible to the output and ground pins.
Larger capacitor values and lower ESR improves dynamic
parameters.
Enable Operation
The enable pin CE may be used to turn the regulator on and
off. The IC is switched on when a high level voltage is
applied to the CE pin. The enable pin has an internal pull
down resistor. If the enable function is not needed, connect
the CE pin to VIN.
PCB Layout
Make the VIN and GND lines as large as possible. If their
impedance is high, noise pickup or unstable operation may
result. Connect capacitors C1 and C2 as close as possible to
the IC, and make wiring as short as possible. The tab under
the XDFN package is internally connected to GND: it is best
practice to connect it to GND on the PCB, but leaving it
unconnected is also acceptable.
Output Discharger
The D version of the NCP4626 includes a transistor
between VOUT and GND that is used for faster discharging
of the output capacitor. This function is activated when the
IC goes into disable mode.
Current Limit
This regulator includes fold-back type current limit
circuit. This type of protection doesn’t limit current up to
